To machine the block, I would go to The Machine Shop in Liberty, MO. I know Kevin. He is a stand up guy. He can recomend a place to do the balancing (I don't think he does it there). I had my balance done at Heit (SP) Automotive in Grain Valley, otherwise know as VAMP Racing. Did mine on my 5.8 years ago and at 6K, you could put a cup of coffee on the intake and it would not spill it. Smooth from idle to the pill at 6k.
Dixons Chilli at 40 Hwy. and Blue Ridge Cutoff in Independence has good chilli. You will not be disapointed.
